822431 ÷ 51 
Let's see how many times 51 fits into 822431.

Going ahead to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 51

Advancing to step 2:
51 goes into 82 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 82 and we're left with 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 51

Moving on to step 3:
The number 51 fits into 312 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtract 306 from 312 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 51

Moving on to step 4:
51 goes into 64 1 times with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
Subtract 51 from 64 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 51

Going ahead to step 5:
133 divided by 51 is 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 1612.0
Deduct 102 from 133 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 51

Advancing to step 6:
51 goes into 311 6 times with a remainder of 5.
The next digit of our result is 6. 
Result so far: 16126.0
Subtract 306 from 311 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 51, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 16126.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 51 fits into 500 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 16126.09
Subtracting 459 from 500 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
When dividing 410 by 51, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 16126.098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
If we divide 20 by 51, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 16126.098
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
The number 51 fits into 200 3 times, leaving a remainder of 47.
The next digit of our result is 3. 
Result so far: 16126.09803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
51 goes into 470 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 16126.098039
Subtracting 459 from 470 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
If we divide 110 by 51, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 16126.0980392
If we take 102 away from 110, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 51 is 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 16126.09803921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 16126.09803921 and a remainder of 2.9e-08.
